TigerCampus explains the AP Chemistry exam format:

The AP Chemistry exam consists of two main sections, each evaluating different aspects of a student’s chemistry knowledge and skills.

多项选择部分：

• 学制： 1小时30分钟
• 问题数量： 大约 60 个问题
• 重量： It contributes 50% to the total exam score.

In the multiple-choice section, students encounter a wide array of questions covering various chemistry topics. This section assesses their comprehension of chemistry concepts, including both theoretical understanding and factual knowledge. Additionally, it may include questions that require students to analyze data, interpret graphs, and work with chemical equations.

免费回复部分：

• 学制： 1小时45分钟
• 问题数量： Comprising 7 questions (3 long free-response questions and 4 short free-response questions)
• 重量： It contributes 50% to the total exam score.

The free-response section challenges students to apply their chemistry knowledge to specific scenarios and problem-solving. It includes a mix of long free-response questions, which often demand more extensive responses involving explanations, calculations, and sometimes even laboratory work, and short free-response questions that tend to be more focused and may involve calculations or brief explanations.

评分：

The AP Chemistry exam is scored on a scale ranging from 1 to 5, with 5 representing the highest achievable score. Generally, a score of 3 or higher is considered a passing score and can potentially earn students college credit and advanced placement in college courses related to chemistry. However, the specific score requirements for credit and placement may vary depending on the college or university.
